Unit 2: Productivity



From Tutor2U

New figures  that make international comparisons of productivity suggest that the UK is once more falling behind efficiency improvements made in some of our major trade rivals. The productivity gap is regarded by many as one of the key supply-side weaknesses in the British economy.

According to the Office for National Statistics, output per hour worked (a measure of labour productivity) in the UK was 15 percentage points below the average for the rest of the G7 industrialised nations in 2011, the widest productivity gap since 1995. On an output per worker employed basis, UK productivity was 20 percentage points lower than the rest of the G7 in 2011

The deep recession of 2008-09 and the sluggish recovery since then also seems to be having an effect on productivity. The ONS reports that, since the start of the recession in 2007, UK output per worker has fallen by a cumulative three percentage points. This is the weakest of all G7 economies apart from Italy.

Reading:


The productivity problem  (Chris Dillow, Investors Chronicle)

Background on productivity
Productivity measures the relationship between inputs into the production process and the resultant outputs.
Productivity can be measured in several ways: e.g.
Output per worker or hour of labour
Output per hour / day / week
Output per machine
Unit costs (total costs divided by total output)
Higher labour and capital productivity can provide the economy with a number of advantages over time.

Lower average costs:
Improvements in labour and capital productivity allow businesses to produce output at a lower average cost (i,e exploit economies of scale) These cost savings might be passed onto consumers in the form of lower prices, encouraging an expansion of demand, higher output and possibly an increase in employment.

Improved competitiveness in international markets:
Productivity growth and lower unit costs are key determinants of the international competitiveness of British firms in domestic and overseas markets. From improved productivity, businesses can develop (or protect) a competitive advantage in markets where there is intense price and non-price competition from overseas suppliers. 

Higher profits:
Efficiency gains resulting in rising productivity are a source of larger profits for companies. These profits might be re-invested through higher capital investment or research and development.

Higher real wages:
In the long run there is a positive relationship between improvements in labour productivity and the real wages paid to labour as a factor of production. Millions of employees in the modern labour market have some element of performance-related pay in their overall earnings package.

Long Run Economic Growth:
It is clear that the capacity of the economy to produce goods and services depends on the stock of factor resources available (i.e. the active labour supply, the stock of capital inputs and natural resources) plus the productivity of those factors.

Unit 4: Globalisation definition

Globalisation is the process by which the world is becoming increasingly interconnected as a result of massively increased trade, information and cultural exchange.

Unit 2: Measuring living standards

GDP per capita is the traditional measure of living standards in an economy - it is a useful tool of comparison but it has its limitations:

•Inequalities = distribution of income
Hidden economy
Ignores externalities
Population sizes
Political environment
The human cost – the number of hours worked
Production does not = consumption

There are several other measures of living standards that we can use to give us an ide
about life inside a country. Life expectancy  birth rate and death rate are all interesting as
is the literacy rate. Some people use the number of mobile phones per person as an
indicator of living standards. 

Your task is to research the following measures of living standard and explain why they 
may give a more accurate picture of living standards and why they may not!


  • Life expectancy 
  • Infant mortality rate
  • Literacy rate
  • HDI
  • OECD's better life index
  • Inclusive wealth index

Unit 2: Triple dip recession

From tutor2u


National output declined by 0.3% in the final three months of 2012 bringing into focus the real possibility of the first ever triple dip recession for the British economy. Growth has been weakening for some time; consumers are under pressure, capital investment remains subdued and our export industries are being hit by low demand in key export markets -despite a competitive exchange rate. Overall real GDP showed no growth at all in 2012 and the level of national production of goods and services remains well below the height reached just before the recession first arrived in 2008. 

The OECD estimates that the trend growth rate for the UK economy is now less than 2% per year. A new normal growth rate this low poses many questions for businesses that have perhaps been waiting for a stronger rebound in confidence and spending to happen.

Unit 3: Contestable Market example

Students taking their Business Economics unit exam this week might like to use online file-storage as an example of a contestable market. This comes during the week of an announcement by the colourfully-named internet tycoon Kim Dotcom of a re-launch of his file-sharing cloud-site Mega - which offers up to 50 Gb of free file storage and out-trumps its big and more established competitors at Dropbox, Microsoft and Google. According to Mr Dotcom he already has a quarter of a million registered users and over a million hits on his website within the first day.


There is no such thing as a perfectly contestable market but the online file-storage ticks quite a few of the boxes in terms of being highly contestable:

1.Low barriers of entry - the most significant barrier Mr Dotcom faces is a legal one. His previous website Megaupload was closed down by international government authorities claiming that it was predominantly used for file-sharing of illegally copied music and movie media. He'll have to prove that the new website isn't blighted by the same activity. Other than that, the set up costs are relatively low and the market is too youthful to have a hugely brand-loyal customer base.

2.Access to technology - the fact that a non-US based internet company can gain such a large following so quickly shows the relative ease of setting up a business of this nature and attracting a large customer base in a short period of time - all thanks to the wonder of playing-field-leveling internet.

3.Low sunk costs - no doubt most of the hardware used by Mega is the same set of servers used by Megaupload and, should Mr Dotcom fall foul of the authorities again and have to quickly shut down I'm sure the same pieces of kit can be easily transferred to another company probably without even moving their location.

Good luck to all students taking exams this week - I hope your results are Mega.

Unit 4: International Trade: The Banana Wars are over!

Andy Reeve explains that a 20 year trade dispute between the European Union and 11 Latin American countries has finally ended, with a historic trade agreement. The agreement was signed in front of Pascal Lamy, the Director General of the World Trade Organisation. The agreement was originally made in 2009, but has taken three years for all nations to ratify.

Unit 3: Whi is Lego so Expensive but popular?

Why Legos Are So Expensive — And So Popular


January 16, 2013

A lot of people wonder how Lego, selling a now un-patented product, can command both massive market share and sell at twice the price of the nearest competitor: Megablocks.

Rhett Allain, in his WIRED article addressing why lego sets are so expensive, unsatisfyingly concludes “Honestly, I don’t know much about plastic manufacturing – but the LEGO blocks appear to be created from harder plastic. Maybe this would lead them to maintain their size over a long period of time.”

While lego offers a superior product, that doesn’t wholly account for why they sell so well.

Chana Joffe-Walt offers a much better explanation in her NPR Planet Money article:

Lego did find a successful way to do something Mega Bloks could not copy: It bought the exclusive rights to Star Wars. If you want to build a Death Star out of plastic blocks, Lego is now your only option.

The Star Wars blocks were wildly successful. So Lego kept going — it licensed Indiana Jones, Winnie the Pooh, Toy Story and Harry Potter.

Sales of these products have been huge for Lego. More important, the experience has taught the company that what kids wanted to do with the blocks was tell stories. Lego makes or licenses the stories they want to tell.

Lego isn’t just selling a product, they are selling a story. Still, I doubt that alone fully explains the difference.

I think Warren Buffett offers the best explanation. Talking about the brand power of See’s Candies, he comments:

What we did know was that they had share of mind in California. There was something special. Every person in Ca. has something in mind about See’s Candy and overwhelmingly it was favorable. They had taken a box on Valentine’s Day to some girl and she had kissed him. If she slapped him, we would have no business. As long as she kisses him, that is what we want in their minds. See’s Candy means getting kissed. If we can get that in the minds of people, we can raise prices. I bought it in 1972, and every year I have raised prices on Dec. 26th, the day after Christmas, because we sell a lot on Christmas. In fact, we will make $60 million this year. We will make $2 per pound on 30 million pounds. Same business, same formulas, same everything–$60 million bucks and it still doesn’t take any capital.

… It is a good business. Think about it a little. Most people do not buy boxed chocolate to consume themselves, they buy them as gifts—somebody’s birthday or more likely it is a holiday. Valentine’s Day is the single biggest day of the year. Christmas is the biggest season by far. Women buy for Christmas and they plan ahead and buy over a two or three-week period. Men buy on Valentine’s Day. They are driving home; we run ads on the Radio. Guilt, guilt, guilt—guys are veering off the highway right and left. They won’t dare go home without a box of Chocolates by the time we get through with them on our radio ads. So that Valentine’s Day is the biggest day.

Can you imagine going home on Valentine’s Day—our See’s Candy is now $11 a pound thanks to my brilliance. And let’s say there is candy available at $6 a pound. Do you really want to walk in on Valentine’s Day and hand—she has all these positive images of See’s Candy over the years—and say, “Honey, this year I took the low bid.” And hand her a box of candy. It just isn’t going to work. So in a sense, there is untapped pricing power—it is not price dependent.

The reason Lego is awesome and Megablocks is not has as much to do with what’s in the consumers’ mind as the product on the shelf. It’s the experience you have with Lego that makes it so amazing.

Remember the first time you played with Lego? You want to pass that experience off to someone else. No one wants to show up to a kids birthday party and announce to everyone they took the ‘low bid’ on a relatively cheap children’s toy.

Lego is a safe bet and we want to reduce uncertainty.

Unit 4 - Should the UK leave the EU?

Should the UK stay in the European Union?


By Tejvan Pettinger on January 14, 2013 in economics

In the past few years, there have been a noticeable increase in the calls for the UK to consider leaving the European Union. A few years ago, we may have enjoyed complaining about EU directives on the bendy banana (which didn’t really exist) but it was taken as almost sacrosanct that membership of the EU was in the UK’s interest.

What has changed and would we really benefit from leaving – and negotiating a free trade agreement, which enables the benefits of EU membership without the supposed costs?
Should We stay in the EU?

The Ideal of European unity.

The relative peace and prosperity in Europe since 1945, is a huge achievement, given the past century of inter-European conflict. Britain is an intrinsic part of Europe, whether it likes it or not. We should take the opportunity to be a member of the European Union and help maintain this European integration and harmony. If the UK left the EU, we would be increasingly politically isolated.

However, do we need to be a member of the European Union to achieve this? The UK could still contribute to European ideals without signing up for all the political and economic integration that the EU elite wish to pursue. European countries, who have stayed out of the EU, such as Switzerland and Norway maintain friendly relations with Europe.

Free Trade

One of the strongest benefits of the European union is the fact that it is our main trading partner, and membership of the EU has helped reduce trade barriers – both tariff and non-tariff barriers. European trade is critical to the UK economy. Leaving the EU, could put this important aspect of our economy under threat.

The hope of Eurosceptics is that we could leave the political integration of the EU, but maintain all the free trade agreements. Again the model is that Switzerland and Norway have not been disadvantaged by staying out of the European Union. Evidence suggests, the EU would be keen to accommodate the UK as a free trade partner.

“If the British cannot support the trend towards more integration in Europe, we can nevertheless remain friends, but on a different basis. I could imagine a free trade agreement.”

Free Movement of labour and capital

Another benefit of the EU is enabling the free movement of people across borders. According to the European Commission, more than 15 million EU citizens have moved to other EU countries to work or to enjoy their retirement. British people have been able to work and retire in other countries. Migration from eastern Europe has helped fill in labour market vacancies, making the UK labour market more flexible. Migration has also helped reduce the dependency ratio, which improves the governments budgetary position.

Eurosceptics might argue that the free movement of labour from eastern Europe creates more problems. Given housing shortage, mass immigration could put strain on UK housing and aggravate issue of overcrowding

Ease of Studying Abroad.

1.5 million young people have completed part of their studies in another Member State with the help of the Erasmus programme. The possibility to study abroad is considered positive by 84% of EU citizens. (benefits of EU) Higher education is important industry and source of foreign earnings, which could be compromised by leaving the EU.

Again, there is the hope that the UK could maintain free movement of labour, but with more restrictions on the numbers of immigrants from Eastern Europe.

Economic Strength of the EU.

In the post war period, the EU economy performed very well, enabling a sustained increase in real GDP per capita and living standards. This used to be an argument in favour of UK membership.

This is perhaps the biggest weakness now facing the EU. The EU can no longer point to economic stability and strength. Structural problems with the Euro and monetary union, are creating a European Union of austerity, high unemployment and low economic growth. Eurosceptics argue that the political pursuit of the Euro and single currency has been at the cost of economic common sense.

For more details, we can examine the problems of the Eurozone. But, in summary

The Euro fails to account for the divergence in competitiveness, this has caused trade imbalances and lower domestic demand

Bond yields have been higher because of failure of European Central Bank to act as lender of last resort. Higher bond yields have created the necessity for unsuitable austerity policies.

The German dominated ECB prioritise low inflation and monetary stability over more practical goals like full employment and positive economic growth.

However, it is worth pointing out that the UK did not join the Euro, so is not sharing in the costs of a single currency. However, the economic performance of the UK hasn’t been much better than our Eurozone partners. Leaving the EU, wouldn’t change that much. We are not in the Euro anyway, and the ECB will not change their economic policy, just because the UK left the EU.

Cost of Membership.

The Treasury state that the net cost of the EU was £7.6 billion, in 2010-11 - up from £4.7 billion in 2009-10. This is relatively small percentage of UK government spending (e.g. social security accounts for £194bn) The UK does benefit from some EU spending, and the structural funds help to reduce regional inequality in the EU. Supporters of the EU argue that this £7bn isasily be funded by the increased trade and lower consumer prices resulting from EU membership

However, sceptics argue the actual cost is closer to £10 billion. Furthermore, much of EU spending is highly inefficient and wasteful. Despite reforms, the biggest target of EU spending is still agriculture, which benefits economies with big agricultural sector. The UK gains little from the common agricultural policy; some of the main recipients are large wealthy landowners who perversely benefit from the subsidies they are entitled to.

Democracy in a global economy

Many issues like fishing, agriculture, global warming, competition policies are issues that need European agreement. In today’s highly global economy, you can’t tackle these issues independently. If fishing policy. is inadequate, the UK needs to work within the structure of the EU to improve it. Leaving will mean the UK have no say, and will be even worse off. We don’t have any choice, but to work for European wide agreement on these issues of a global nature.

However, critics argue that the EU has become so large and cumbersome, that it is too difficult to have a meaningful say on important issues. Increasingly issues will have to be decided by Qualified Majority Voting, which means that the UK may have to accept rules and regulations we didn’t support.

Personal View

My personal view is instinctively to support attempts at European union and integration. Even if there are some costs, like inefficient agricultural policies, the hope is that the net benefits outweigh this. In particular, I don’t feel that the UK can go it alone – which some Eurosceptics seem to give opinion. The nature of globalisation is that we are increasingly integrated and interdependent on our European neighbours (whether we like or not).

However, I can also see the attraction of the viewpoint which says – why not have the benefits of European membership (free trade, acceptance of qualifications, free movement of capital) without all the unnecessary political integration and economic policies which are damaging the EU. You can often find yourself agreeing with people, even if you don’t share their motives.

In particular, the attitude of the EU towards the Single currency and unemployment is a real cause for concern. In my view, the Single currency is structurally unsound, and rather than bringing European nations together, is causing a rise in extremist political activity, because of the high social costs surrounding the consequences of austerity and high unemployment.

The management of the EU crisis makes you wonder at the direction of the European Union and whether they are losing sight of the best way to promote European integration.

One final note is that leaving the EU, would change things much less than either side might admit. Trade may be relatively unaffected. There is no reason why leaving the EU, should have to significantly change the way we do business. But, also leaving the EU, wouldn’t change the problems arising from the Single Currency experiment. Also the money saved from leaving the EU would be relatively insignificant. It wouldn’t make much of a dent in the UK budget deficit.



Unit 4: Overseas Aid & Economic Development

Does aid help or hinder economic growth and development? This is the subject of a fierce debate in the development economics literature


Aid has a range of economic, social, environmental and political objectives

Economic development can take place without aid - China and Vietnam have both experienced sustained and rapid growth over nearly two decades without receiving much in the way of international aid payments measured as a share of their GDP

Well directed and targeted aid can enhance a country's growth potential but the effects may not be seen for many years

Aid that might help finance the building of a power station contributes directly to aggregate demand and increases supply potential

Aid that is designed to put more children through school or humanitarian aid to vaccinate kids and prevent them dying will have an impact over a longer time horizon

Different kinds of aid projects can affect growth at different times and to different degrees

Building the Case for Overseas Aid

Overcoming the savings gap: Aid provides a financial inflow for low income countries - it helps to overcome the savings gap. Also important in stabilising post-conflict environments - e.g. generate jobs to keep fighters away from conflict

Building the Capital Stock: Project aid can fast forward investment in critical infrastructure projects - an increase in the capital stock lifts a country's growth potential

Human Capital and Post Conflict Help: Long term aid for health and education projects - builds human capital and raises productivity. Aid combined with good policy can have lasting positive effects

Higher Growth and Trade Spillovers: Well targeted aid might add around 0.5% to growth rate of poorest countries - this benefits donor countries too as trade grows

Counter arguments – Limits / Disadvantages of Overseas Aid

Corruption: In poorly governed countries much of the aid is expropriated and leaves the recipient country.

Ruiling Elites: Aid can act as a barrier to true democracy - politicians pay more attention to aid donors than to their citizens

Aid dependency: A dependency culture on aid might be generated - the aid paradox is that aid tends to be most effective where it is needed least

Market distortions: Aid for example in the form of food aid in emergencies may lead to a distortion of market forces and a loss of economic efficiency

In the "The Bottom Billion" Professor Paul Collier from Oxford University suggests that, ceteris paribus, overseas aid may have added around 1% per year to the growth rate of the poorest countries of the world during the past 30 years. There are few economists who argue that aid has led to a reduction in economic growth of donor countries. Most of those who are critical of overseas aid focus instead on dependency and corruption. It is possible for countries to grow quickly without aid – but equally there are countries who were initially heavy aid recipients who have grown and developed and are now aid donors themselves for example South Korea.

The ceteris paribus assumption is important. Aid can provide a much needed injection of funds for some of the world's poorest countries and communities - but everything else is not equal. Many external factors may reduce or enhance the impact of aid on economic growth, for example the quality of government, the efficiency of financial systems and also the absence of conflict.

Key point: The contribution aid makes to growth differs sharply in countries at peace and countries in conflict

Aid Graduates – Countries whose overseas aid as a share of GDP has declined over the years
Critics of much of the aid that has gone to Africa in recent decades argue that a high proportion of aid has gone to low-income countries with poor institutional regimes. The UK Coalition government has a target of allocating 0.7% of GDP to overseas development assistance (ODA) - this target came into being in 1970 and has never been revised! But is it right to stick rigidly to such a target independent of what else is happening in both the domestic and the global economy? 0.7% of UK GDP is forecast to equate to around £15 billion in 2015. The government is also eliminating financial aid to India.

Unit 4: Comparative Advantage

Comparative advantage is a dynamic concept meaning that it can and does change over time. For a country, the following factors are important in determining the relative unit costs of production:




1. The quantity and quality of factors of production available for example some countries have an abundant supply of good quality farmland, oil and gas, fossil fuels. Climate and geography have key roles in creating differences in comparative advantage.

2. Different proportions of factors of production – some countries have abundant low-cost labour suitable for volume production of manufacturing products.

3. Increasing returns to scale and the division of labour – increasing returns occur when output grows more than proportionate to inputs. Rising demand in the markets where trade takes place helps to encourage specialisation, higher productivity and internal and external economies of scale. These long-run scale economies give regions and countries a significant advantage.

4. Investment in research & development which can drive innovation and invention

5. Fluctuations in the exchange rate, which then affect the relative prices of exports and imports and cause changes in demand from domestic and overseas customers.

6. Import controls such as tariffs, export subsidies and quotas – these can be used to create an artificial comparative advantage for a country's domestic producers.

7. The non-price competitiveness of producers - covering factors such as the standard of product design and innovation, product reliability, quality of after-sales support. Many countries are now building comparative advantage in high-knowledge industries and specializing in specific knowledge sectors – an example here is the division of knowledge in the medical industry, some countries specialize in heart surgery, others in pharmaceuticals.

8. Institutions – these are important for comparative advantage and important for growth too. Banking systems are needed to provide capital for investment and export credits, legal systems help to enforce contracts, political institutions and the stability of democracy is a key factor behind decisions about where international capital flows.

Comparative advantage is often a self-reinforcing process.



Entrepreneurs in a country develop a new comparative advantage in a product either because they find ways of producing it more efficiently or they create a genuinely new product that finds a growing demand in home and international markets

Rising demand and output encourages the exploitation of economies of scale; higher profits can be reinvested in the business to fund further product development, marketing and a wider distribution network. Skilled labour is attracted into the industry and so on

The expansion of an industry leads to external economies of scale.



Unit 4: The World Trade Organisation

The World Trade Organisation (WTO) is a multi-lateral organisation based in Geneva, Switzerland with 156 countries.

 
It helps to promote free trade by persuading countries to lower their import tariffs and other barriers to open markets including widespread use of import licences, export subsidies and other non-tariff barriers
 
The WTO was established in 1995 and was preceded by the General Agreement on Tariffs and Trade (GATT).
 
Membership of the WTO has expanded with the successful admission of China, India and latterly, Russia to the WTO as an event of huge significance.
 
Russia is the most recent country to join the WTO. Countries that join the WTO have to introduce a large number of economic and legal changes and agree to abide by established global trade rules
 
The WTO oversees the rules of international trade
  • It provides a forum for settling trade disputes between governments
  • It has the power to levy fines when breaches of global trade agreements have occurred
  • It seeks to make trade between countries transparent
Countries that join the WTO are required to achieve sustained reductions in average import tariffs. After WTO entry in July 2012 Russia’s average import tariffs will decline from 9.4% to 6.4% on industrial goods and from 15.6% to 11.3% for agricultural goods.
 
Is the influence of the WTO reducing?

There has been rapid growth of bi-lateral trade agreements between countries rather than through multi-lateral trade agreements. Non-tariff barriers proliferate and the WTO does not seem to have been effective in curbing these types of protectionism. The WTO has found it hard to make progress in dismantling entrenched systems of agricultural protection / financial support especially farm policies in advanced nations. This has led many critics of the WTO to argue that the WTO is run in the interests of manufacturers and farmers in the developed world - there are strong protectionist interests within the WTO framework.

How might the below story impact demand?

http://www.bbc.co.uk/news/world-us-canada-21002381


Unit 1: Information Failure

Health campaigns such as these here are attempts to correct market failure by raising consumers awareness about the negative externalities associated with smoking. In other words they aim to correct information failure.

Do you think that these clips actually work?
What is the opportunity cost of videos such as these?
What would be a more effective method?

Here are some examples of policies aimed at trying to reduce the negative externalities caused by eating junk food. 

This video clip here has found research that says that educating students at schools about the dangers of drugs would actually encourage students to take drugs!!

Unit 1: Rail Fare Rises

In the UK rail fares have risen by more than 4% (more than inflation) to pay for improvements to the rail network. 

This has angered many commuters who rely on the train to get in and out of work.

Have a look HERE and HERE for more information. 

Things to think about:

How will this impact labour mobility?

Aren't trains supposed to be 'green alternatives' to cars - shouldn't we be subsidising them?

Who should provide rail transport - the Government or private firms? Why?


Unit 1: Public goods


Public goods are non diminishable, non rivalrous and non excludable. Light houses and street lights are often cited as examples. If it was left to the free market to supply these goods they would be underprovided as people can 'free ride.' Lets say that Brendan decided to put a streetlight outside his house - he could not stop Carl, his next door neighbour from using or benefiting from it (non excludable).

Another good example of public goods is flood defence schems. This winter the UK suffered from heavy rains. The government has been critisied in the past from not spending enough on flood defence - did they do enough this year? Watch this VIDEO  and this VIDEO for more information.





The UK is not the only country in Europe to suffer from flooding - Venice whilst famous for its canals is also sinking. Watch THIS clip from more information. 

Things to think about:

a) Are these flood defences non-excludable?
b) Are these flood defences non-rival?
c) So, are these flood defences a pubic, quasi-public or private good?



Unit 1: Smoking and Market Failure

The latest attempt to stop people smoking is a hard hitting advert that shows a tumor growing out of a cigarette.

Click on this link HERE for more information.




Questions to think about:

What are the negative externalities associatied with smoking

What methods does the Government already use to stop smoking - which is the most effective and why?

What would a negative externality diagram WITH tax look like?

How does a tax on cigarettes affect consumer and producer surplus?

Unit 3: Revision advice for Jan examination

Some excellent advice for the upcoming Unit 3 exam...
